Description

Technical Field

[0001] This utility model relates to the technical field of endoscope processing equipment, specifically to an optical fiber stretching and pressing device. Background Technology

[0002] An optical endoscope is a diagnostic instrument that combines optics, ergonomics, precision mechanics, modern electronics, mathematics, and software technologies. It enters the human body or an object through a long, thin tubular device to observe and diagnose.

[0003] Currently, in the process of assembling endoscopes, a spacer is usually inserted manually between the optical fiber and the outer tube, and then the optical fiber is pulled to make the optical fiber and the spacer fit together, so as to assemble the endoscope.

[0004] However, during the bonding process of the optical fiber and the spacer, adhesive needs to be applied to the surface of the spacer. Because the adhesive reduces the friction on the surface of the spacer, it is easy for the optical fiber to be squeezed and floated up during the bonding process. This makes it impossible to guarantee the shape and area of ​​the optical fiber at the end face, resulting in uneven distribution of the optical fiber at the end face of the endoscope and irregularity of the optical fiber end face caused by the floating of the spacer. This leads to poor light uniformity and uneven images when using the endoscope, resulting in misdiagnosis and missed diagnosis. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an optical fiber pulling and pressing device to solve the technical problems in the existing assembly methods of endoscopes in the background art, such as uneven distribution of optical fibers on the end face and irregularity of the optical fiber end face caused by the floating of the gasket.

[0006] The present invention provides an optical fiber pulling and pressing device for assembling an endoscope, the endoscope including an optical fiber disposed on an outer tube and a gasket for mounting on the outer tube.

[0007] The tensioning and pressing device includes a support frame, and tensioning components, fixing components and pressing components disposed on the support frame;

[0008] The fixing component is located on one side of the support frame and is used to fix the outer tube. The pulling component is movably connected to the other side of the support frame in multiple directions. The pulling component is used to fix the optical fiber and, through the multi-directional movement of the pulling component relative to the support frame, the optical fiber is pulled along the end face of the gasket.

[0009] The pressing assembly is located above the fixing assembly. The pressing assembly includes a sliding bracket that is slidably connected to part of the support frame, and a pressing block that is raised and lowered on the sliding bracket. Through the relative movement of the sliding bracket and the pressing block, the pressing block slides along the end face of the pad to attach the optical fiber to the pad and install the pad inside the outer tube.

[0010] Furthermore, the support frame includes a base plate, a support column disposed on the base plate, at least one sliding plate and at least one sliding block, the sliding plate being slidably connected to the base plate, and the pulling assembly being slidably connected to the sliding plate through the sliding block;

[0011] The sliding direction of the sliding plate is different from the sliding direction of the pulling component.

[0012] Furthermore, the pulling assembly includes a concave member, a convex member, a rotating shaft connected to the sliding block, and at least one adjusting member;

[0013] Either the concave part or the convex part is rotatably connected to the rotating shaft. The concave part and the convex part are connected by the adjusting member, which is used to adjust the fixed gap between the concave part and the convex part. The fixed gap is used to fix the optical fiber.

[0014] Furthermore, the concave member is rotatably connected to the rotating shaft.

[0015] Furthermore, the pulling assembly also includes a first fixing member, which is screwed onto the concave member and restricts the rotation angle of the concave member relative to the rotating shaft.

[0016] Furthermore, the fixing component includes a fixing sleeve, which is disposed on the base plate and is used to fit one end of the outer tube.

[0017] Furthermore, the fixing assembly also includes multiple fixing brackets, which are spaced apart along the length of the support column, and each fixing bracket fixes a different part of the outer tube.

[0018] Furthermore, the fixed bracket includes a support plate with an arc-shaped receiving portion, and a second fixing member screwed onto the support plate, the second fixing member being disposed opposite to the arc-shaped receiving portion.

[0019] Furthermore, the pressing assembly also includes a pressing member, and the pressing block is connected to the pressing member.

[0020] Furthermore, the pressing assembly also includes an elastic element, and the pressing block is raised and lowered on the sliding bracket via the elastic element.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In the fiber optic pulling and pressing device of this utility model, the arrangement of the support frame, fixing component, pulling component, and pressing component allows for the initial fixation of the outer tube during endoscope assembly. The fixing component first fixes the outer tube, and the pulling component, which is movably mounted on the support frame in multiple directions, can move to a position close to the fiber end to fix the fiber end. The pulling component is then moved to allow the fiber to adhere to the surface of the pad. Finally, the pressing block is manually pressed to allow part of the fiber end to adhere to the pad. Since the pad is installed at an angle on the outer tube in practice, the sliding bracket is pushed to slide while the pressing block is pressed, allowing the pressing block to slide along the inclined direction of the pad, thereby adhering the fiber end to the pad. At the same time, the pad can be pressed into the outer tube to complete the assembly of the endoscope. The relative movement of the pressing block and the sliding bracket ensures uniform fiber distribution and avoids the technical problem of the pad floating up and causing irregular fiber end faces.

[0033] Please see Figures 1-6 The image shows an optical fiber pulling and pressing device according to one embodiment of the present invention. The pulling and pressing device is used to assemble an endoscope. The endoscope includes an optical fiber 110 disposed on an outer tube 100 and a gasket 120 for mounting on the outer tube 100. It should be noted that in some actual situations, the endoscope also includes other components, such as an inner tube disposed inside the outer tube 100. Since other components are conventional prior art in this field, they will not be specifically described here.

[0034] To address the technical problems of uneven distribution of fiber optic cables 110 on the end face and irregular end face of fiber optic cables 110 caused by the floating of the gasket 120 in the existing assembly method of endoscopes, in this embodiment, the pulling and pressing device includes a support frame 200, a fixing component 400, a pulling component 300 and a pressing component 500 disposed on the support frame 200.

[0035] The fixing component 400 is located on one side of the support frame 200 and is used to fix the outer tube 100. The pulling component 300 is movably connected to the other side of the support frame 200 in multiple directions. The pulling component 300 is used to fix the optical fiber 110, and the optical fiber 110 is pulled along the end face of the gasket 120 by the multi-directional movement of the pulling component 300 relative to the support frame 200.

[0036] The pressing assembly 500 is located above the fixing assembly 400. The pressing assembly 500 includes a sliding bracket 510 that is slidably connected to a portion of the support frame 200, and a pressing block 520 that is raised and lowered on the sliding bracket 510. Through the relative movement of the sliding bracket 510 and the pressing block 520, the pressing block 520 slides along the end face of the pad 120 to attach the optical fiber 110 to the pad 120 and to install the pad 120 inside the outer tube 100.

[0037] In practice, the outer tube 100 is initially fixed using the fixing component 400. At this time, the end of the optical fiber 110 is located outside the top of the outer tube 100. The pulling component 300 is movably mounted on the support frame 200 in multiple directions, allowing the pulling component 300 to move to a position close to the end of the optical fiber 110. The pulling component 300 is used to fix the end of the optical fiber 110. Then, the pulling component 300 is moved so that the optical fiber 110 can be attached to the surface of the gasket 120. Finally, the pressure block 520 is pressed manually to position part of the end of the optical fiber 110 against the gasket 120. For the bonding process, given that the pad 120 is installed at an angle on the outer tube 100 in actual practice, the sliding bracket 510 is pushed to slide while the pressure block 520 is pressed, so that the pressure block 520 can slide along the inclined direction of the pad 120, thereby bonding the end of the optical fiber 110 to the pad 120. At the same time, the pad 120 can also be pressed into the outer tube 100 to complete the assembly of the endoscope. In this example, the relative movement of the pressure block 520 and the sliding bracket 510 can ensure that the optical fiber 110 is evenly distributed and avoid the technical problem of the pad 120 floating up and causing the end face of the optical fiber 110 to be irregular.

[0038] To facilitate understanding of this case, in this embodiment, the support frame 200 includes a base plate 210, a support column 220 disposed on the base plate 210, at least one sliding plate 230, and at least one sliding block 240. The sliding plate 230 is slidably connected to the base plate 210, and the pulling component 300 is slidably connected to the sliding plate 230 through the sliding block 240. The sliding direction of the sliding plate 230 is different from the sliding direction of the pulling component 300. It should be noted that slide rails are correspondingly provided on both the base plate 210 and the sliding plate 230. Specifically, the slide rail on the base plate 210 allows the sliding plate 230 to move laterally and reciprocally, and the slide rail on the sliding plate 230 allows the sliding block 240 to move vertically and reciprocally. By utilizing the lateral and vertical reciprocating movements, the pulling component 300 can move in two directions.

[0039] In some preferred embodiments, an adjusting bolt can also be provided on the sliding plate 230. When the sliding plate 230 moves laterally, the adjusting bolt can be rotated to fix the sliding plate 230 to the base plate 210, so as to limit the movement of the sliding plate 230.

[0040] Furthermore, in this embodiment, the pulling assembly 300 includes a concave member 310, a convex member 320, a rotating shaft 330 connected to the sliding block 240, and at least one adjusting member 340. Either the concave member 310 or the convex member 320 is rotatably connected to the rotating shaft 330. The concave member 310 and the convex member 320 are connected by the adjusting member 340. The adjusting member 340 is used to adjust the fixed gap between the concave member 310 and the convex member 320. The fixed gap is used to fix the optical fiber 110.

[0041] Specifically, the concave member 310 is rotatably connected to the rotating shaft 330, and the pulling assembly 300 also includes a first fixing member 350, which is screwed onto the concave member 310. The first fixing member 350 restricts the rotation angle of the concave member 310 relative to the rotating shaft 330. In a specific embodiment, the fixing gap between the concave member 310 and the convex member 320 can be adjusted by the first fixing member 350, so that the optical fiber 110 can be embedded in the fixing gap. It should be noted that the rotating shaft 330 can be fixedly connected to the sliding block 240.

[0042] Furthermore, in this embodiment, the fixing component 400 includes a fixing sleeve 410 and a plurality of fixing brackets 420. The fixing sleeve 410 is disposed on the base plate 210 and is used to fit one end of the outer tube 100. The plurality of fixing brackets 420 are spaced apart along the length direction of the support column 220. The plurality of fixing brackets 420 fix different parts of the outer tube 100 respectively. Specifically, the fixing bracket 420 includes a support plate 421 with an arc-shaped receiving portion and a second fixing member 422 screwed onto the support plate 421. The second fixing member 422 is disposed opposite to the arc-shaped receiving portion.

[0043] The bottom of the outer tube 100 can be fitted with the fixed sleeve 410, and multiple fixed brackets 420 can be used to fix the middle, top, upper middle and lower middle parts of the outer tube 100, thereby ensuring the stability of the outer tube 100. Specifically, the outer wall of the outer tube 100 can be attached to the support plate 421 by setting the arc-shaped receiving part, and the second fixing member 422 can fix the outer tube 100 in the support plate 421 by rotating the second fixing member 422.

[0044] In some preferred embodiments, to facilitate the operation of the pressing member 530, the pressing assembly 500 further includes the pressing member 530 and the elastic member 540. The pressing block 520 is connected to the pressing member 530, and the pressing block 520 is raised and lowered on the sliding bracket 510 through the elastic member 540.

[0045] It should be noted that the first fixing member 350, the adjusting member 340 and the second fixing member 422 mentioned above can all be adjusting bolts.

[0046] In summary, the fiber optic stretching and pressing device of this invention, compared with existing endoscope assembly methods, has at least the following advantages:

[0047] In the fiber optic stretching and pressing device of this invention, the arrangement of the support frame 200, fixing component 400, stretching component 300, and pressing component 500 allows for the following steps during endoscope assembly: First, the fixing component 400 initially fixes the outer tube 100. Then, the stretching component 300, movably mounted on the support frame 200 in multiple directions, allows it to move to a position close to the end of the fiber optic cable 110, securing the end of the fiber optic cable 110. Next, the stretching component 300 is moved to allow the fiber optic cable 110 to adhere to the surface of the gasket 120. Finally, the pressing block 520 is manually pressed to press the fiber optic cable 110 into place. The end of the fiber optic cable 110 can be fitted with the position of the pad 120. In practice, the pad 120 is installed at an angle on the outer tube 100. At this time, while pressing the pressure block 520, the sliding bracket 510 is pushed to slide, so that the pressure block 520 can slide along the inclined direction of the pad 120, thereby fitting the end of the fiber optic cable 110 onto the pad 120. At the same time, the pad 120 can also be pressed into the outer tube 100 to complete the assembly of the endoscope. Through the relative movement of the pressure block 520 and the sliding bracket 510, the fiber optic cable 110 can be evenly distributed, and the technical problem of the fiber optic cable 110 end face being irregular caused by the pad 120 floating can be avoided.
